SPECIFICATION forming part of Letters Patent No. 310,572, dated January13, 1885.

(No model.)

Z'o LZZ whom, it may concern:

Be it known that I, Jarras C. Fanzine, a citizen ofthe United States,residing at Vassar, in the county of Tuscola and State of Michigan, haveinvented certain new and useful Improvements in Flour-Bolts, of whichthe following is a specification,reference being had therein to theaccompanying drawings.

Figure l is a longitudinal section of a centrilugal reel containing myinvention. Fig. 2 is an end elevation ot' the same, portions of thecasing being broken away. Fig. 3 is a vertical section on line w fr,Fig. l. Fig. et is a vertical section showing the invention applied toan ordinary form of bolting-rcel. Fig. 5 is an elevation of the head endor receiving end of the bolt shown in Fig. 4.

Similar letters of reference indicate like parts in all the iigures.

The frame and casing may be of any usual `or approved construction, inwhich A is the head end, A the top or deck, and A2 the casing at thetailA end of the machine.

A A. are vertical partitions arranged at both ends a short distanceinside of the easing, and provided with circular openings to Ieceivellanges of the reel-heads, as will be hereinafter explained.

The upper conveyer-box, in which the conveyer B works, has its tail endconstructed of a downwardly-extendcd portion, c, of the partition A atthat end ol' the machine, the end b at the head end of the conveyer-boxconsisting of a separate part arranged farther from the front end ot'the casing and upon the opposite side of a crossgirt, A", from that towhich the l'ront partition, A", is attached. The bottom ol' thisconveyer-boX, as well as the bottom of the conveyer-box C, is providedwith a number of cut-offs, (marked, respectively, b c.)

D is the central beater-shaft.

E E are the spokes or arms, each set rotating from a central hub, whichis keyed to the beater-shaft.

F F are the beaters, which may be mounted upon spider-arms E, `or disksattached to the beater-shaft.

G G is the feed spout or hopper, the horizontal extension Gf of whichis, by preference, circular in cross-section.

d is a worm attached to the beater-shaft D,

and operating to discharge material from the hopper into the interior ofthe reel.

H is a distributing-plate mounted upon the beater-shaft a short distancefrom the inner end of the horizontal part G of the hopper.

I l l2 are the reel-heads, each having a central opening with a flangeor shoulder, t', another llange, shoulder, or rib, fi', of greaterdiameter, and an inner iange, shoulder, or rib, 2, of less diameter, allof these flanges or shoulders being circular, the inner one fittingclosely the outer opening in the partition AJ.

J J are frictional supporting and driving rollers keyed to a sha-ft, J,in such position as to engage with the outer faces of the flanges jj areanti-friction guiding-rollers arranged upon opposite sides ofeach head.rllhese guiding-rollers are mounted upon the inner ends of shafts y" j,and are keyed thereto, the shafts rotating in boxes or bearings a a.(See Fig. 2.)

K is a bevel-pinion keyed to the projecting end of the beater-shaft, andmeshing with a `bevel-wheel, K', mounted on the upper end of uprightshaft Ft.

K3 is a friction driving-wheel, the hub of which is grooved to receivethe arms it', which project horizontally from a vertical plate, 702,which is secured to a vertical post, A5, of the frame-work by means ofbolts a2, which pass through a vertical slot, a, of such length as willpermit the friction driving-wheel K3 to be let down from the positionshown in Fig. l so far that it will engage with the opposite or lowerside of its engaging wheel J2.

At the opposite end of shaft J is a setscrew, J 2, mounted in across-girt or other suitable support, with its inner end bearing againstthe end of said shaft in such manner that by turning the screw in theproper direction the driving-wheel J2 can be caused to impinge upon thewheel K3 with such force a-s to rotate the reel. By preference, I inserta steel spindle, J3, in the socket in the end of shaft J to receive thethrust of the set-screw; but this spindle may be omitted.

From the above description it will be understood that by properlyshifting the position of the friction driving-wheel K3 the'speed of therotation of the reel can be varied, as can the direction of itsrotation.

C2 C3 represent bevel-gears mounted upon IOO the vertical shaft Iv2 andthe conveyor-shaft for driving the conveyers.

Motion is communicated to the beater-shaft by belting its pulley D2 toany suitable motor which will drive the beaters in the directionindicated by arrow 2, Fig. 2.

L L represent longitudinal bars or ribs attached'at their ends to theouter flanges or ribs, t fi', of the reel-heads.

In Figs. 1, 2, 3 the outer face of the reel is many-sided, as at M M,having longitudinal bars L L and hoops, as indicated at N, Figs. 1 and3.

O is a brush extending longitudinally of the reel, its central core orbase being journaled at its ends and supported upon vibrating arms o.(See Figs. 1 and 3.) These links may be either pivoted to some portionof the framework or casing of the bolt, or they may be hung upon ashaft, I), which extends the entire length ofthe machine, and is mountedat its ends in the partitions A" Ad, as shown in Fig. 1.

In operating this reel or bolt the material which is fed in by the Wormd is caught by the rotating, corrugated, or ribbed plate II and properlydistributed to the beaters F at thel head end of the reel.

Vhen desired, an opening maybe made in the feed-spout of hopper G, witha slide or other cover, for the admission of air in suitable quantities.

In Fig. et the invention is shown applied to an ordinary bolting-reel,in which Q is the central shaft. q q are the spokes or arms, carryingthe longitudinal bars of a many-sided reel. The shaft Q, is, bypreference, provided with an ordinary Wing-gudgeon, the shank or journal1- of which is mounted in a suitable bearing on the frame, and carriesat its outer end a i'rictioirwheel, J, there being by preference at theopposite end of the shaft setscreW j, for forcing the wheel J againstthe friction driving-wheel K", which is mounted upon a vertical shaft,K2, driven from any desired motor. The hub of this friction driving-Wheel is grooved and mounted in a sliding bearing in substantially thesame manner as is the corresponding driving-wheel and bearing in Fig. 1,and hence need not be specifically described.

Although I have shown in Fig. et but two bolts arranged in a chest, oneabove the other, it is evident that any desired number might besimilarly arranged and driven in the same manner. It will of course beunderstood, particularly When the axis of the reel is inclined, that byturning the screw j" backward the engagement of the Wheel Ji With thefriction driving-Wheel K3 may be relieved so that the reel Will cease torotate, and thus any one or all of the reels may be permitted to standstill without interfering with the continuous rotation of shaft K2.

I am aware that friction-gearing has been used for drivinggrain-scourers in which the operative parts have rotary motion, and donot claim such construction; but it is evident that many advantagesarise from the construe tion which I have shown in both styles ofboltsto wit, a horizontal driving-shaft projecting through the casing ofthe bolt-chest, with a wheel mounted on the projecting end of the' shaftto rotate in a vertical plane, in combination with ay drivingfriction-Wheel mounted upon avertical shaft and rotating in a horizontalplane-because, among other things, such construction makes it possibleto shift the driving-wheel to points both above and below the center ofthe driven Wheel, and thus change the direction of rotation of the reel.

Ido notin this case claim anything except what is specifically set forthin the claims hereof, reserving to myself the right to claim all othermatter not therein set forth but shown in the drawing or described inthe specifica tion in another application which I am preparing to file.

That I claim is- A 1. In a flour-bolt, the combination of ahorizontalreel, an inclosing-casing, a horizontal shaft, one end of which projectsin front of the end of the casing, a driven friction-Wheel mounted uponthe projecting end of the h`orizontal shaft, and a friction drivingwheelrotating in a plane at right angles to the plane of the driven wheel andengaging with the driven wheel, substantially as set forth.

2. In a ilour-bolt, the combination of a horizontal reel, aninclosing-casing, a horizontalshaft, one end of which projects in frontof the end of the casing, a driven friction-wheel mounted on thehorizontal shaft and rotating in a vertical plane, and an adjustablefriction driving-Wheel rotating in a plane at right angles to the'planeof the driven wheel and engaging with the driven wheel, .substantiallyas set forth.

3. In a flour-bolt, the combination, with a horizontal shaft, one end ofwhich projects in front of theinclosing-casin g, of a slotted standardat right angles to the horizontal shaft,and a friction driving-Wheelmounted on the slotted standard and adjustable relatively to the drivenwheel, substantially as set forth.

4:. In a flour-bolt, the combination, with the horizontal shaft, oneendof which projects in front of the casing, of a driven friction-Wheelmounted on the projecting end of the horizontal shaft, and a frictiondrivingwheel mounted on an axle at right angles to the horizontal shaft,and adjustable on a line at right angles to the horizontal shaft,substantially as set forth.

5. rIhe combination, in a our-bolt, of the beater-shaft, the verticalshaft driven by the beatershaft, the friction driving-Wheel rotated bythe vertical shaft, the supporting and driving wheels mounted on ahorizontal shaft, and the vertical wheel mounted upon said shaft andengaging with the friction driving-Wheel, substantially as set forth.

(5. In a Hour-bolt, the combination, with IOO IIO
